(9*10)+(15*1) = 105
15 tens = 150

There are 15 with a remainder of 6
If I'm figuring this correctly, 16*10 = 160 and 15*1 = 15, so 160 + 15 = 175.
16 tens=160, 160+15 ones=175. The answer is 175.

The order of magnitude is "tens".
150/10=15
60.45
(9*10)+(15*1) = 105
15 tens = 150
You can't subtract 15 ones from 15 tens. The bills are all tens, so you'd have to get change first. Then you'd be subtracting 15 ones from 13 tens and 20 ones, or from 13 tens, one 5, and 15 ones.

Currently it is not rounded to anything. You can round 14.5 to the nearest tens place. When you round it to the tens place you will get: 15. This is because the ".5" value in the decimal.
